Marw

Marw (Merv), in present-day Turkmenistan in the historic region of Khurasan, was one of the largest cities of the medieval Islamic world and a major centre of learning. The early Qur'an commentator Muqatil ibn Sulayman (d. 767) is associated with the Khurasan-Marw and Balkh sphere of early exegesis. [NOTE: this node duplicates 'merv' — same coordinates ~37.66/62.17.]
